pitch~
Hi i am using pitch to try and locate frequencies on a piano. I want to locate three but the results are rather strange.when i play one note the result is fine but when I play more than one its strange. how does it read frequency when two or more notes are played together?

There is an external called transcribe which does polyphonic pitch detection.
It’s performance depends greatly on the source material. I found
that a piano recording with the gain turned up pretty high can get
some decent results.
Give it a try…

ya il give it a try. im building a patch that I need to detect the notes I play live on a piano and thus depending on what it reads it will for example begin a delay.
